I hurt my wrist a work and once I got home I was rubbing the area that hurt when I discovered a pea size lump that was moving when I moved my hand. If you hold your right hand in front of your face so you could wave hello to yourself and put your thumb just below your wrist line and your other fingers just below your wrist line (make an alligator mouth) and wave at yourself. It rolls back and forth between my fingers. I can not feel it on the under side nor does it hurt. It does fade in and out with pressure and there may be smaller ones. Any ideas? I am planning an appointment but, that's a few days away. I appreciate any response. Thanks.
